Who investigated the growth of the brain?
Epstein (1978)
1 of 15
What did Epstein find?
consistent spurts in brain growth at 3-10 months which led to increase in brain weigh of 30% by the age of 1.5. This also occurs during the ages of 2-4,6-8,10-12,14-16 increments in brain weigh 5-10% in each of these 2 year periods.

What did Maguire's study show us?
the brain can alter in structure depending on stimulation from the environment and this plasticity suggests the possibility of recovery from brain injuries.
3 of 15
What can Brain plasticity cause (e.g. damage)
other brain structures and neurons developing differently. Trauma does not only affect the areas that are damaged directly, it also disrupts other sites and circuits. (if child has injury has different effect than adults)

How do the Wernicke's area and the Broca's area work together?
Wernicke's produces the language that the Broca's ensures is articulated by controlling speech muscles.

When does Grey matter begin to decline?
Around 6-7 years, follows through adolescence
6 of 15
How does the environment influence brain development in adolescents?
Connections which are not used are eliminated. Allows brain to become more efficient in its use of energy, removing weaker links in favour of strengthening those that are required. Pre-frontal cortex on of last ones to undergo this
7 of 15
What did Zuckerman find?
A significant positive correlation between sensation seeking and IQ. People who exhibit stronger sensation-seeking drives are no less able to exert control over their behaviour
8 of 15
Who investigated brain activity in relation to risk taking (not Barkley-Levenson)
Eshel et al (2007)
9 of 15
What did Eshel look at?
difference in brain activity when adults and adolescents faced a choice between alternatives that had a high probability of a small reward or a low probability of a high reward
10 of 15
What did Eshel find?
More brain activity in the occipital frontal cortex in the adults when they made a risky choice. Showing that if the occipital frontal cortex was not developed in adolescents they would not be able to rely on this area of the brain to control choices
11 of 15
What is a GDL drivers scheme?
A probation period for new drivers
12 of 15
Why is the GDL drivers scheme needed?
adolescent risk taking often occurs in groups, having peers present can make the reward more appealing, so reducing opportunity should lower risk
13 of 15
Who investigated the GDL schemes for drivers 17-19?
Kinnear et al
14 of 15
What did Kinnear (2013) find?
Effective at reducing collisions. However, depends on number of restrictions implemented and how strictly they are enforced by authority
